Neutral Grounding Resistors
Generator Neutral Grounding &
MOTOR STARTING REACTORS
Inverter Braking Resistors
Motor Starting &
Harmonic Filter Resistors Motor starting reactors are used for starting
Current Limiting Resistors large 3 phase motors while limiting inrush
RC Filters currents. Large motors generally use 6 times
more current than their nominal current.
Normally, they are started with 70 % of
REACTORS voltage and the rest of the voltage, that is
normally about 30 %, is dropped across the
Current Limiting Reactors motor starting reactor. After 15 - 20
Neutral Grounding Reactors seconds, the reactor is switched off with
Shunt Reactors contactors in the system.

The height and the diameter of the reactor can be adjusted to customer specific needs in order to
meet unusual space requirements
Complete installation guidelines are provided with the
reactors in order to meet required magnetic clearances on
close metallic structures. Each reactor is supplied with an
INSTALLATION GUIDELINES that specifies minimum
magnetic clearances for the reactor.
Aluminum, hot dip galvanized steel or concrete support
stands are designed for specific applications.
All the routine tests are performed in accordance with EN 60289 or other standards depending on
customer request. Type test reports are available on request. All the test reports are submitted to
Basic testing program includes some or all of the following tests:
• Routine Tests (Inductance, Resistance, One Minute AC Insulation Voltage Withstand Test and
Impulse Voltage Withstand Test)
• Short Circuit Withstand Test
• Temperature Rise Test
• Sound Level Test
• Seismic Test
